Home Generators

Backup Generators

Years ago, backup generators were only used for emergency lighting in hospitals and medical facilities, but now they are common in houses. Home generators in Wilmette are usually natural gas-fueled and are controlled by a transfer switch. A transfer switch is constantly monitoring the building power. As soon as the transfer switch senses a lack of power from the power within seconds the generator starts. As soon as the transfer switch senses a lack of power from the electrical provider such as ComEd, within seconds the generator starts.

Generator Size

A load calculation of your house determines what size home generator in Wilmette is needed. This has become easier in more recent years due to smart transfer switches. A number of the large loads (AC, Electric Oven, Electric Car Charger, Electric Heat etc.) can be wired through low voltage relays built into the transfer switch. The smart transfer switch will sense when the generator is close to capacity and start shedding those large loads one at a time until the generator is below its capacity. This is very important since the generator will simply shut itself off if it is overloaded.

If you don’t want to pay for the whole house generator make a list of the items you would like to have stay on in case of a power outage. The list will be included in the load calculation to determine the size of the home generator in Wilmette.

  • Furnace
  • Sump pump
  • Refrigerator
  • AC
  • Wine Cellar
  • Master bedroom lights

Generator Maintenance

Generators need regular maintenance. All generators exercise themselves once a week to ensure that the battery is charged, and the unit is ready for action. We have many regular yearly maintenance agreements with our customers. Our electrician will come out and change the air filter, oil filter and spark plugs as well as install new oil.

You can monitor your generator remotely to ensure that it will start in an emergency. All generator manufacturers have electronic monitoring systems for their new models. This is an added cost but very helpful for many homeowners. If the generator fails to exercise, an email or text message will be sent to multiple addresses or phones. If the generator shows a bad battery, low oil or a number of other functions an alert is sent to the homeowner.

We are serving throughout the Chicago area and along the North Shore, including Evanston, Glencoe, Glenview, Highland Park, Kenilworth, Lake Forest, Northbrook, Northfield, Wilmette and Winnetka.
